Press Release from Capricorn:
Capricorn introduce the new ONE restrictor set. Provided in three different heights but all in the 9mm diameter, the restrictors have been conceived to be used on all Novarossi and OS on-road engines and designed in order to fine tune the response of your engine. The lower restrictor is meant to improve the bottom end power, while the high one increases the top speed, all three giving different feelings to the user.
